Typical ApplicationsOil & Gas: Flow control valves (refineries, ethylene plants)Power Generation: Boiler/turbine valve regulationWater Treatment: Precision control of water quality valvesPharma/Food: Process control in sterile environments5. Key AdvantagesSmart functionality: Auto-calibration, remote monitoring, predictive maintenanceHigh reliability: Non-contact design for harsh operating conditionsFlexible integration: Multiple protocol options for control system compatibilityFor detailed technical documents, refer to SAMSON official manuals or authorized distributors.working principleThe 3730-2/3 digital electrical valve positioner is assembled onto the pneumatic control valve. valveThe locator receives electric control signals output by the control system or controller, according to the predeterminedSet up a relationship to assist the pneumatic actuator in adjusting valve position and achieving accurate positioning. valveThe locator will input control signals (given parameter w) and control valve position stroke or rotationCompare and process the feedback of the angle (adjusted parameter x), and then output the corresponding gasSend the dynamic control signal (output parameter y) to the pneumatic actuator.The 3730-2/3 digital electrical valve positioner is mainly composed of a microprocessor (5)Electronic units, analog electrical converters, output pneumatic amplifiers, and electronicsComposition of valve position sensor system (2).When the input control signal changes or there is a valve position deviation, apply pressure to the pneumatic actuatorOr release pressure. If necessary, the output gas volume can be adjusted to improve the signal pressure effectSet the output signal pressure limit value by software to 1.4, 2.4, or 3.7 bar.The gas volume regulator (9) with a fixed set value can maintain a constant gas volume for emptying,Used for positive pressure blowing inside the valve positioner housing and optimizing the output capacity of the pneumatic amplifier.Provide constant pressure from the gas source pressure regulator (8) to the electrical converter (6)The gas source is not affected by changes in external gas source pressure.Input control signal 4 to 20 mATravel range3.6 to 200 mmOpen angle from 24 degrees to 100 degreesMaterialAluminum alloyCompany ProfileCertificationsFAQQ: Is the product authentic?A: All the products we sell are new and original genuine products with one year warranty.Q: How long is the product delivery time?A: We have our own warehouse and a large number of stock products, regular models we have in stock, special models we need to factory order and can be delivered quickly.Q:Do you have a price advantage?A: Some of the products we are the authorised agent in China region, the price we all have competitive advantage.
